Prisoner of Iraq: Get essentially held hostage, likely in exchange for a US pullout. Get shot when it doesn't happen.
Prisoner of Bush: Never! *shoots self*
Probably get interrogated, put in a little cage, and given the full Stalin treatment.
It's not fun either way, but nobody ever said being a POW was. Since neither side is gonna feel really obligated to go by the Geneva Convention (Bush because he already doesn't, Saddam because he and all his officers are pretty much dead and might as well hurt as many enemies as they can as badly as they can), I think I'd rather not be taken alive by either side.
Anyway, this thread is lame. Making predictions in a completely unpredictable situation is lame. There's a possiblilty that everything will go swimmingly for Bush, he'll find all sorts of bioweapons and a secret conspiracy with France, Germany, and Russia after the war, and send some "Iraqi" who's spent the last 30 years plotting revenge on 80% of Iraq from Washington and loves Bush unquestioningly to be the new dictator. There's a roughly equal possibility that the US army will end up fighting civilian militias in the streets of Baghdad, while Turkey, Saudi Arabia, and Iran undergo bloody coups and have their governments replaced by virulently anti-US reactionaries who have absolutely no qualms about biobombing Israel and the east coast of the US, triggering a nuclear exchange and causing China to see its opportunity and invade from California, resulting in a bio/chemo/nuclear war that leaves the Midwest a bioactive crater, sets the whole world into a nuclear winter, and kills off 90% of humanity. Moreover, everyone on every side of the conflict is a bastard, including the US and Iraqi people (excepting the Kurds) who put up with this crap and let their leaders stay in power. The Kurds, they're fine and all power to them- they actually tried to do something about it after the Gulf War, and woulda succeeded if the US hadn't shafted thm. Now we're doing it again in selling them out to Turkey, which makes them doubly cool in my opinion. Maybe they should get Iraq and Washington.
